There will be a ground at the control panel that you can use. Ground is ground so whether you connect direct to the battery negative or to the ground at the control panel it is the same thing.

Ok thank Rob
Those instructions seem to be for perfect conditions. The first time i hooked it up i plugged into the ground with all the 12v neutral wires The only reading was the volts nothIng else. Ill hook it up again and give it a minute. See what happens.
Thanks for the help

The shunt for that meter needs to be connected in series with the negative cable + two wires from the shunt into the meter so it measures amps thru the shunt.

There was another install a bit like this: 12 Volt Power Meters https://www.mygrandrv.com/forum/show...l=1#post208544
Two shunts were used.
One to measure current out of the converter into the fuse panel.
One to measure current in/out of the battery.

The attached drawing shows a shunt wired in near the fuse panel.
